松辽盆地北部古龙断陷深层火山岩油气藏勘探潜力分析

Exploration Potential of Volcanic Reservoirs of Gulong Rift in Northern Songliao Basin

利用重、磁、电、震与火山岩地质学相结合的多手段分析方法,研究了古龙断陷火山岩的分布及发育特征。结果表明,古龙断陷火山岩非常发育,岩性主要以中酸性火山岩为主,岩相主要以爆发相和溢流相纵向上互层,古龙断陷深层火山岩油气藏的勘探潜力较大。

The distribution and developmental characteristics of the volcanic rocks in Gulong rift were studied by gravity,magnetic,electricity and seismic exploration.The results indicate that the volcanic rocks in Gulong rift were mainly composed of intermediate——acidic rocks,and in the rift volcanic rocks were well grown.Explosive facies and overflow facies are interbeded.As a result,the volcanic reservoirs in this area have great exploration potential.
